Box



Jan. l, 1963 P. A. oPRoMoLLA Box Filed March l, 1961 ;VENTOR Bf f i"C749: ORNEY/ United States Patent Oitce senate Patented Jan. 1, 1963This invention relates to boxes, and more particularly to wooden cratesor carriers, such as used for handling and shipping milk bottles orcartons.

Boxes of the character indicated must be of sturdy and comparativelyinexpensive construction and be capable of sliding on the flooring oftrucks without catching and breakage. It is known practice to furnishthe bottom of such boxes with two or more generally parallel metalshoeing members, extending the length of the box and serving as skids toprotect the wood of the box and also to provide rounded edges or ends tofacilitate passing over irregularities. Boxes of this type arecomparatively expensive, and it is the general object of the presentinvention to provide a box having comparable advantages in operation butrequiring the use of much less metal and providing for a very simpleattachment of the metal shoeing elements.

With this object and still others which will appear in the followingdescription in mind, the invention consists in the combinations andarrangements of parts and details of construction which will now iirstbe fully described with reference to the accompanying -drawing and thenbe more particularly pointed out in the appended claims.

In the drawing:

FIG. 1 is a side elevation View of the box of the invention;

FIG. 2 is an end elevation view ofthe box;

FIG. 3 is a bottom plan view ofthe box;

FIG. 4 is a detail fragmentary section on the line 4-4 of FIG. 1;

FIG. 5 is a detail section on the line 5 5 of FIG. 2;

FIG. 6 is a fragmentary section on the line 6 6 of FIG. 2;

FIG. 7 is a fragmentary bottom plan view showing one corner of the box;

FIG. 8 is a similar view of one of the shoes;

FIG. 9 is a reverse view of the shoe; and

FIG. 10 is a section on the line Iii-10 of FIG. 7.

The box may contain a number of milk bottles or cartons, B, of any ofthe usual sizes, and the example chosen for illustration contains twelvequart milk bottles of usual shape. The side walls 2, end walls 3 andbottom 4 are composed of rectangular wooden panels, each of these panelsbeing formed of two or more boards joined together as by means of tongueand grooving and gluing connections, as is usual, the separate boards ofthese panels meeting along the various joint lines x. The end walls havehand-holes 5 (FIG. 2) for lifting and holding the box. The ends of theside walls are rebated as indicated at 6 (FiG. 4), and the bottom issimilarly rebated as indicated at 7 (FIGS. 5 and 6), the bottom beingordinarily thicker and being rebated to a greater depth than the sides.Metal reinforcing straps 9 are wrapped around the ends of the box, andare secured to the box by means of nails or drive screws 10, which alsoserve to secure the sides and bottom 2, 4 to the box ends 3. Therebating of the side walls 2 is relatively 4shallow so that the straps 9are slightly recessed or substantially iiush with the side walls 2,while the straps are positioned considerably above the bottom of thebox, generally, by reason of the deeper rebating of the bottom 4.

Each of the tour corners of the bottom 4 is diagonally slotted asindicated at 11, forming a triangular isolated raised portion 12 at eachcorner of the bottom and metal shoes 13 (FiGS. 8, 9) tit over thesetriangular corner portions 12, as indicated. Each shoe 13 has a diagonalange i4- received in a slot 11, end and side ilanges 15', 16 fittingaround the corner of the box bottom or unrebated portion thereof. Theshoe 13 has a central boss 17 and extends down below the level of thebox bottom generally by the thickness ot its metal plus the thickness ofthis boss,

as appears clearly from the figures (FIGS. 6, 10). The center of theboss 17 is depressed and perforated as indicated at 18 and receives arivet 19 securing the shoe to the box bottom. As will be evident, asliding movement of the box against any kind of a ledge or edge willengage against the rounded surfaces of the shoes i3 adjacent the flangesthereof and against the rounded edges of the bosses 17, thus providingsubstantially complete protection of the box bottom against impact ofany such obstructions and also protecting the wood of the bottom againstabrasion in sliding.

What is claimed is:

1. A rectangular wooden carrier box comprising side walls, end walls anda bottom, the bottom having a diagonal slot adjacent each of itscorners, and a triangular metal protecting shoe secured at each cornerof the bottom, the said shoe having anges around its edges overlappingthe side and end of the bottom corner and tting into the said slot.

2. A rectangular wooden carrier box comprising side walls, end walls anda bottom, the bottom having a diagonal slot adjacent each of itscorners, and a triangular metal protecting shoe secured at each cornerof the bottom, the said shoe having anges around its edges overlappingthe side and end of the bottom corner and fitting into the said slot anda domed central portion extending below the level ofthe box bottom.

3. A rectangular wooden carrier box according to claim 2, in which thesaid shoe has an aperture and recessed area in the middle of said domedportion, the inside of the said recessed area abutting against the boxbottom, and comprising also securing means passing through the saidaperture.

4. A rectangular wooden carrier box according to claim 3, in which thesecuring means comprises a rivet passing through the box bottom.

5. A rectangular wooden carrier box comprising side walls, end walls anda bottom, the bottom being rebated at each end and having a diagonalslot adjacent each of its corners, and a triangular metal protectingshoe secured at each corner of the bottom, the `said shoe having iiangesaround its edges overlapping the side and rebated end of the bottomcorner and fitting into the said slot.

6. A rectangular wooden carrier box according to claim 5, comprisingalso a metal strap around each box end and Ireceived in the rebated endof the box bottom so as to be above the level ofthe said shoes.

7. A rectangular wooden carrier box according to claim 6, in which theends of the box side walls are also rebated and the straps are receivedin the rebated portions thereof.
